In these design patterns, identify common communication patterns between objects and realize these patterns. These patterns are also concerned with algorithms and the assignment of responsibilities between objects. Iterator Pattern [Sequentially access the elements of a collection] This pattern lets you traverse elements of a collection without exposing its underlying…

Structural patterns are concerned with how classes and objects are composed to form larger structures. Structural class patterns use inheritance to compose interfaces or implementations Composite Pattern [A tree structure of simple and composite objects] This pattern is used where we need to treat a group of objects similarly to…

These patterns provide a way to create objects while hiding the creation logic rather than instantiating objects. example: encapsulation. In simple words, these patterns provide various object creation mechanisms, which increase flexibility and reuse of existing code. Singleton Pattern [A class of which only a single instance can exist] This…

The best designers use many design patterns Design Pattern Design patterns are general, reusable solutions to solve common problems in software design. Each pattern is like a blueprint that you can customize to solve a specific problem in your code. Categories of Design Patterns In GoF (Gang of Four) we have 3 categories of Design Patterns …

Nowadays we are hearing from different sources and companies, that their developers test their own features/code and they don’t need any QA resource for testing. Also, people usually say, “we don’t need to hire a QA resource, our developers perform all testings and we trust them” This sounds amazing and…

What exactly does it mean to build a scalable application? At a first level, it is just connecting users with remote resources by using the Internet. The part that makes it scalable is that the resources. When it comes to an application architecture, there are a few things which we…

The adoption of CI/CD will change the way, how developers and testers deliver their applications. This enables the confidence of team members to reliably release their applications or infrastructure code at any time through the automated Deployment Pipeline. …
